I have got my 16.5 update by manually downloading the file by using norton update center website..and it allowed me download a small file and that small file downloaded the 16.5 version of NIS 2009 for me..and also it automatically removed my previous one and installed the new one..and this 16.5 update is really awesome!! new features are just great!..detection of the severe threats are given in less time with the difference of 2-5 hours. This has made symantec the leading security software comapany..i have myself checked various threats that get dected by norton and not by others..and i am curious to know about internet explorer 8 compatibility..please someone tell me about norton compatibility with IE 8 this is going to release in a short time..
Thanks to Norton (Symantec)Team
